This study aims to classify the biotope types based on the vegetation community in built-up areas by different land use and to map the plant communities. By classifying biotopes according to a taxonomic system, the characteristics of a biological community can be well-represented. The biotope classification indexes for the target area include human behavioral factors such as land use intensity, land-use patterns and land-cover types. The type classification was divided into four hierarchic ranks starting with Biotope Class, next by Biotope Group and Biotope Type and lastly by Biotope Sub-Type. The Biotope Class was first divided into two areas: the areas improved by humans and the areas unimproved by humans. The improved areas were again divided into permeable and non-permeable regions on the Biotope Group level. In the Biotope Type level, permeable paving areas were divided into areas with wide gap pavers and those with narrow gap pavers. The differential species of each biotope type are Lindera glauca, Conyza canadensis, Mazus pumilus, Vicia tetrasperma, Crepidiastrum sonchifolium, Zoysis japonica, Potentilla supina and Festuca arundinacea. The results of this study suggest that the biotope classification methodology, using a subjective phytosociological approach, is a useful and valuable tool and the results also suggest the possibility of applying more objective and scientific methods in mapping and classifying various environments.

This study is conducted to investigate number of species in various habitat size in the area of urban biotope in Seoul from October to November in 2001 and from May to June in 2002. It is established that habitat size does not significantly affect the number of species in urban biotope. Thirty-two bird species were observed in 54 sites. Thirteen species of birds used sites of up to 1㏊, 29 species from 1 to 10 ㏊, and 8 species in the sites larger than 10㏊. We find that most of species appeared in size (1-10㏊), rather than in size (<1㏊, >10㏊). The cumulative number of species for a given cumulative area was consistently higher when small sites were added first. We think that this habitat size is the actual area to promote number of species within the urban area. Also, there was significant increase of number of species at biotope with water source and multiple vegetation structure. Therefore, if water resources and multiple vegetation structure is maintained, even small area can be helpful to the bird species promotion.

We investigated the vegetation structure in Cultural Heritage Site of Odaesan National Park using 52 quadrats for each type of land use to figure out some characteristics of plant biotope. As we classified vegetation communities, they are six groups of communities. distinguished species in two of them are Taraxacum officinal, Erigeron annuus and Poa pratensis which are common in urban areas. Distinguished species in one of them are Potentilla fragarioides var. major which is common in outskirt of forest. And Distinguished species in another 3 communities are Sasa borealis and Quercus mongolica which are common in forest. Using TWINSPAN and DCA, we are able to classify the six communities into 3 types biotope (temple-biotope, slope-biotope, forest-biotope) in Cultural Heritage Site. The dominant species of urban-biotope are Poa pratensis, Artemisia prinseps and that of slope-biotope is Tripterygium regelii. Also the dominant species of forest-biotope are Quercus mongolica, Abies holophylla and Ulmus davidiana var. japonica. We could see more species in slope-biotope than another biotope types. Moreover, in urban-biotope types, we could find many of naturalized plant species.

To provide more natural elements in the harsh urban environment, 'planting trees as urban forests' has been emphasized as having an important role, and trees are expected to be as functional as the trees under more natural conditions in rural areas, and provide people with benefits. To do this, urban forest policies needed a better idea of planting methods and management of trees through the theory of landscape ecology, and also the feedback system according to the evaluation and assessment of urban forests. In this case study, a new principle and assessment indices for the evaluation are applied for the 4 urban forests in two Korean metropolitan cities, Daejeon and Ulsan. The evaluation of Korean urban forest-function as biotope and the assessment for the classification of biotope diversity types are carried out. The AUEM(Adding Up Estimation Matrix) is applied for the analysis of urban forests. Unlikely previous researches on the other Korean metropolitan cities, the size of urban forest has less influence on the vegetation diversity. The most frequent biotope grade is the 3rd grade at Namseon park and Mt. Hamwol, while Mt. Bomun and Mt. Yeompo show the 4th grade. The grades of forest-function as biotope are from 3rd to 5th in which lower than average in forest-function grades. This means that the 4 sites are still not-matured forests and less-functional forests as the urban biotope.

This study aims to classify the biotope types and evaluate its functions for acquiring the basic information which can support the landscape ecological management of the urban forest in the case of the three parks in Daegu metropolitan city and then to analyze vegetation landscape patterns. The biotope classification was mostly divided into 5 to 6 biotope type groups in the high units and 15 to 20 biotope types belong to them and then could know that the more big the park size, the more diverse and large the biotope types and its average area. The biotope grade over the three parks was dominating low rank grade (1 to 3 grade) 72.7% that forest organism is inadequate as live, and high grade (7 to 9 grade) did not appear entirely. Most in Biotope function estimation were appeared less than the middle rank grade and biotope area is bigger, those grade rises and temperature could know that is fallen. Vegetation landscape patterns was very simple because only two kinds of Robinia pseudo-acacia and Quercus acutissima is appeared as the dominated landscape elements in all of the three parks. And also because average area of those elements is generally 1ha or so, there was much problems in consecutiveness of functional role as forest ecosystem component. Conclusively, Ecological landscape management need to improve Biotope diversity and functionality, and it secures ecological minimal area and space linkage.

The purpose of this research is to identify the selection status of the evaluation index in Korea and suggest improvements. In order to do so, comparison and analysis are conducted of terms, items and measures for biotope evaluation indexes attested in related documents published in domestic and foreign areas. The findings of this research are listed in the following. First, terms about biotope evaluation indexes are used and integrated with each other. Second, items used to denote biotope evaluation indexes are largely different in each region since comprehensive concepts have not been established for selecting the items. Third, there are poor grounds for items denoting biotope evaluation indexes to the species of creatures. Fourth, the items cannot provide satisfying explanations for the relative values of the current condition in the urban ecosystem of a specific region. The results of this research may be applied to provide basic materials about what is to be improved for selecting biotope evaluation indexes in Korea. In order to systematically preserve an urban ecosystem environment in Korea for the future, it is necessary for the state to develop and set up such evaluation indexes and guidelines that reflect the relative values of biotopes in each level of urban areas in Korea.

This study was conducted to provide a database for biotope conservation and restoration of the Jeonju region in North Cheolla Province. To accomplish this task, investigations were made on the characteristics of the distribution pattern of naturalized plants in the region. From May to June 2008, the flora and lists of naturalized plants were investigated and, based on these data the ratio of naturalization was calculated. The results of this investigation areas follows: a total of 113 families and 54 species were found in the flora. The naturalized plants among them amounted to 19 families and 54 species. The ratio of naturalization was most high in the biotope type of rural dried stream(36.4%). The biotype that showed the lowest ratio of naturalization was coniferous natural forest type, which had no naturalized plants in it. The average naturalization ration of the Jeonju region turned out to be 18.9%, which is similar to that of other mid-size cities in Korea.
